Take her out of the house for a walk in the morning and in the evening also.
Give him some objects to play with so that he will indulge in them and will be happy alone.
I recently a see a similar dog with coloring it's looking awesome, so don't worry it will look different than other dogs.
I also have 4 month old black Nox. He is attending basic training only twice a week, in my concern it's enough to train him at this stage.
